System And Method For Visibility Enhancement
First Claim
1. A system for visibility enhancement for a motor vehicle assistant system for warning the driver of hazardous situations comprising:
- a first sensor means comprising a camera installed in a rear view equipment of the motor vehicle adapted to record at least one image;
a second sensor means adapted to generate at least one position profile of at least one object located within a critical range of the first sensor means; and
an image processing means adapted to;
receive a first input signal from the first sensor means containing the at least one image and a second input signal from the second sensor means containing the at least one position profile of the at least one object located within the critical range, andmanipulate the at least one image to generate a manipulated image by(i) altering the contrast of that part of the image that shows the at least one object located within the critical range, wherein altering the contrast of that part of the image that shows the at least one object located within the critical range comprises increasing the contrast, and(ii) altering the contrast of that part of the image that does not show the at least one object located within the critical range, wherein altering the contrast of that part of the image that does not show the at least one object located within the critical range comprises decreasing the contrast.

Abstract
A system for visibility enhancement comprises a first sensor means comprising a camera adapted to record at least one image. A second sensor means is adapted to generate at least one position profile of at least one object located within a critical range of the first sensor means. An image processing means is adapted to receive a first input signal from the first sensor means containing the at least one image and a second input signal from the second sensor means containing the at least one position profile of the at least one object located within the critical range. The image processing means further manipulates the at least one image to generate a manipulated image by altering the contrast of that part of the image that shows the at least one object located within the critical range. A corresponding method of visibility enhancement is also disclosed.
